WR-28 Dual-Polarized Scalar Feed Horn Antenna

SAF-2334431535-328-S1-280-DP is a broadband WR-28 Ka-Band dual polarized scalar feed horn antenna that covers several popular 5G bands in the frequency range of 23 to 44 GHz. The antenna features an integrated orthomode transducer (OMT) that provides high port isolation and cross-polarization cancellation and a broad band scalar horn that provides low sidelobe levels. The OMT enables the antenna to separate a circular or elliptical polarized waveform into two linear, orthogonal waveforms or vice versa. The dual polarized horn also supports either vertical or horizontal polarized waveguide forms with 35 dB typical cross polarization rejection. At center frequency, the horn antenna exhibits 15 dBi nominal gain and a typical half power beamwidth of 35 degrees and -25 dB sidelobe levels, respectively. The antenna exhibits 40 dB typical port isolation between the horizontal and vertical ports. All ports have UG-599/U compatible flanges with 4-40 threaded holes. The OMT (SAT-343-28028-S1), compact square to circular transition (SWT-280328-SA-C-QC), and broadband scalar feed horn (SAF-2234431535-328-S1) can all be purchased separately. Additional customization options, such as converting the waveguide ports to coaxial ports by adding waveguide to coax adapters (SWC-2434431505-282F-R1 or SWC-2434431505-282M-R1), are available under different model numbers.
